10 Dec 2000 | | Subject: | nucl-th hep-ex hep-ph nucl-ex | | Abstract: | An analysis of experimental data, obtained at the Proton Linear Accelerator of INR, is carried out with the aim of searching for supernarrow dibaryons in the pd->p+pX_1 and pd->p+dX_2 reactions. Dibaryons with masses 1904pm 2, 1926pm 2, and 1942pm 2 MeV have been observed in invariant mass M_{pX_1} spectra. In missing mass M_{X_1} spectra, the peaks at M_{X_1}=966pm 2, 986pm 2, and 1003pm 2 MeV have been found. The analysis of the data obtained leads to the conclusion that the observed dibaryons are supernarrow dibaryons, the decay of which into two nucleons is forbidden by the Pauli exclusion principle. A possible interpretation of exited nucleon states with small masses is suggested. | | Source: | arXiv, nucl-th/0101021 | | Services: | Forum | Review | PDF | Favorites | |
